Introduce young learners to the wonders of the human body with the Learning Resources Skill Builders! Human Body science set. Designed for children aged 4 and up, this engaging educational kit combines interactive play with foundational biology concepts to spark curiosity and build school-readiness. Children construct their own 3D human figure using five snap-on biological systems—skeletal, muscular, digestive, respiratory, and circulatory—helping them understand how the body works from the inside out. With the included stand-up body chart and sticker sheet, kids can visually identify major organs and systems. The reusable 24-page write-and-wipe activity book reinforces learning through tracing, sequencing, and fun facts, while the unique x-ray viewer and cards let children "scan" the skeleton to explore internal structures in a magical, hands-on way. Whether used at home, in the classroom, or for homeschool science lessons, this complete set encourages independent discovery, fine motor development, and early STEM learning—all through engaging, child-friendly activities.
